What does a bulb with an exclamation mark on the dashboard mean?

Vehicle dashboard has a bulb with an exclamation mark is the lighting fault indicator, when this indicator lights up, it indicates that there is a fault with the exterior light bulbs, such as brake lights, license plate lights, width indicators, reverse lights, etc. being damaged, or loose connections. It is recommended to go to a 4S store for inspection and repair as soon as possible. The method for replacing car bulbs is: 1. Open the engine hood and locate the lamp cover behind the headlight assembly; 2. Unscrew the lamp cover; 3. Pull out the lamp socket with the power cord, pressing the bulb with your hand to avoid damage; 4. Release the lamp socket clip to remove the bulb, then install the new bulb. When reinstalling the lamp cover, make sure it is tightly screwed to prevent rain and dust from affecting the headlight's lifespan.
I noticed that the bulb symbol with an exclamation mark on the dashboard is quite common—it indicates a fault in the vehicle's exterior lighting system, such as a burnt-out headlight, taillight, brake light, or turn signal, or an issue with the wiring. You might not immediately sense anything wrong since it's hard to see your own lights while driving, but the system detects abnormal current via sensors and triggers the warning light. This is especially dangerous at night, increasing the risk of rear-end collisions or poor visibility. I recall once checking my lights and discovering a burnt-out taillight bulb—luckily, I caught it in time. I recommend inspecting all lights after parking to confirm they're functioning. If you can't identify the issue yourself, visit a professional repair shop or dealership promptly to diagnose wiring problems or replace bulbs—don't compromise driving safety.
